LCLCTC12V 24V Laser Sensor Photoelectric Switch PNP NO NC 4‑Wire

Description

Product Overview

The LCLCTC12V 24V laser sensor is a high‑performance photoelectric switch designed for demanding industrial applications. Built by LCTC, this device combines a compact M18 form factor with a robust 4‑wire PNP NO/NC output, allowing users to select either normally open, normally closed, or both signals to suit a wide range of control circuits. The sensor features a precision laser emitter and a sensitive photodetector that together provide an adjustable detection distance from 8 mm up to 50 mm, giving operators fine control over the sensing zone. With a rapid 1 ms response time, the unit can keep pace with fast‑moving parts on production lines, ensuring accurate detection without missed events.

Durability is a core design principle: the housing is made from high‑impact engineering plastic that resists chemicals, dust, and moisture, while internal circuitry includes short‑circuit and reverse‑polarity protection. The sensor operates on a wide input voltage range of 10‑30 VDC, drawing less than 30 mA no‑load current, and can switch loads up to 200 mA at 30 VDC. Its maximum switching frequency of 500 Hz makes it suitable for high‑speed automation, and the built‑in open‑collector output simplifies integration with PLCs, relays, and motor controllers.

Usage

This laser sensor excels in environments where precise, non‑contact detection is essential. Typical applications include conveyor belt monitoring, robotic arm positioning, packaging line object detection, and safety interlock systems. Because the sensor can detect very small changes in optical signals, it is also effective for counting items, verifying product presence, and triggering downstream processes such as labeling or sorting.

Installation is straightforward: the M18 mounting flange fits standard industrial panels, and the four‑wire connection (power, ground, NO, NC) can be wired directly to a PLC or controller. The adjustable detection range allows users to fine‑tune the sensing window without mechanical adjustments, simply by rotating the sensor head or using the provided calibration screw. The device’s built‑in protection features reduce downtime caused by wiring errors, making it a reliable choice for both new installations and retrofits in existing automation systems.
